Use of LED technology


VMS are equipped with light-emitting diodes which compared with conventional optical fibres have the advantage of an enhanced readability. By use of patented optics the phantom light effect caused by incident solar radiation can be avoided. Additionally, the power consumption is approx. 90 % lower than by using optic fibres. Light-emitting diodes have a considerably longer life-cycle than the previously used halogen bulbs. Therefore, energy consumption, energy and maintenance costs are extensively lower.
